It's springtime in Pittsburgh, and throughout the city, Callery pear trees are sprouting beautiful, white blossoms.
But that's just the problem. Simply put, these trees stink.
"This whole place smells like dead fish," says Sheila Titus. "I mean everywhere. Everywhere you see one of these trees with the white on them."
Titus has lived in her home in the now-hip neighborhood of Lawrenceville for 49 years. Two decades ago, her grandson and his 7th grade class planted a row of Callery pears across the street from her house.
The world's largest ant colony stretches over 3,700 miles. It succeeds, biologist Deborah Gordon says, because no one is in charge. The ants communicate with algorithmic patterns to survive and thrive.
President Obama used the backdrop of the Florida Everglades this Earth Day to highlight the dangers posed by a changing climate. He also took a swipe at Florida's Republican governor, who's been accused of discouraging state workers from discussing global warming.
"Climate change can no longer be denied," Obama said. "It can't be edited out. It can't be omitted from the conversation. And action can no longer be delayed."

It has been about a decade since beekeepers and scientists began documenting a decline in honeybee populations and other important pollinators.
Even if you're not a lover of bees or honey, you should know that bees are critically important to our food supply. They help pollinate billions of dollars of crops each year, from apples and carrots to blueberries and almonds.
So if bees are threatened, ultimately, the production of these crops will be threatened, too.
